Is there any checks when user space ask for a VLAN to be added to a port to see if it is already in use an return -EBUSY or -EINVAL or something? Andrew

The RTL8366 DSA switches will not work unless we set up a default VLAN for each port. We are currently using e.g. VLAN 1..6 for a 5-port switch as default VLANs. This is not very helpful for users, move it to allocate the top VLANs for default instead, for example on RTL8366RB there are 16 VLANs so instead of using VLAN 1..6 as default use VLAN 10..15 so VLAN 1 thru VLAN 9 is available for users.
